Hangarage at Denham: Everything You Need to Know
Why Denham Aerodrome?
Denham at a Glance
Denham Aerodrome (EGLD) is located just 20 minutes from central London, with direct access to the M25 and M40. The airfield has a proud history dating back to the Second World War and today serves as one of the premier general aviation aerodromes in the south-east, with a strong community of helicopter owners, flight training, and maintenance operations.
Indoor vs Outdoor: Why Hangarage Matters
Robinson Service Bulletin Guidance
Robinson Helicopter Company strongly recommends indoor storage for all their aircraft. Their maintenance guidance notes that exposure to the elements accelerates component wear and can lead to findings during mandatory inspections that would not otherwise occur. An aircraft stored outdoors will almost certainly face higher maintenance costs over its lifetime than one that has been properly hangared.

What to Look for in a Hangarage Package
- Ground handling by staff experienced with helicopter operations
- Secure, locked hangar facilities with appropriate monitoring
- Twenty-four-hour access or flexible hours that match your flying patterns
- Adequate clearance for your specific helicopter type and rotor diameter
- Reasonable insurance requirements compatible with your existing cover
- Transparent pricing with no hidden fees for towing, repositioning, or access
Robinson-Specific Dimensions and Considerations
Measuring Up
When assessing hangar space, do not simply measure the door opening. Consider the internal height at the point where your aircraft will actually stand, accounting for any overhead obstructions such as lighting rigs, structural beams, or fire suppression equipment. Allow at least six inches of clearance above the highest point of the rotor mast for safe towing and positioning.
The Twelve-Year Overhaul: Where Hangarage Really Pays Off
A Sound Investment
Consider the maths: twelve years of hangarage at 400 GBP per month totals 57,600 GBP. If proper hangarage saves you 30,000 to 50,000 GBP at the twelve-year overhaul, preserves your rotor blades for their full service life, and extends the lifespan of your canopy panels, the net cost of hangarage over the aircraft's lifecycle is remarkably modest. In many cases, it effectively pays for itself.
Insurance Implications
Check Your Policy
Never assume that outdoor storage is acceptable to your insurer. Some policies contain specific clauses requiring the aircraft to be hangared when not in use. Breaching this requirement, even unintentionally, could void your cover at precisely the moment you need it most. Review your policy documents carefully and confirm storage requirements in writing with your broker.
Making the Right Choice for Your Aircraft
Key Takeaways
- Denham Aerodrome (EGLD) offers exceptional access: 20 minutes from London, close to the M25 and M40
- UK helicopter hangarage typically costs 300 to 600 GBP per month depending on location and services
- Indoor storage is essential for Robinsons, protecting against corrosion, blade erosion, and UV canopy crazing
- Hangared aircraft consistently show better findings at the mandatory 12-year overhaul, saving 30,000 GBP or more
- Insurance premiums are typically 10 to 15 per cent lower for hangared aircraft, saving thousands annually
- Verify dimensional clearance for your specific model: R66 requires approximately 11.5 feet of headroom
